W-Type Air FilterW-type air filter uses thick mini-pleat filter elements in V patterns to increase the filtration area in an effective way,Website: , featuring high air volume, low resistance and long service life, which is mainly used in HVAC systems in the clean room. The filters of this type include different efficiencies ranging from medium efficiency (F6-F9), sub-high efficiency (H10-H12) to high efficiency (H13-H14) for options. W-type filters include box type and W type, with the frames made of plastics, galvanized sheets, aluminum plates, stainless steel plates and plastics sprayed steel plates etc. Standard size & parametersModelOverall sizeL×W×DRated Air Flow  (m3/h)Initial resistance (Pa)H13 Dust holding(g)Efficiency (F6)1μm ≥60%Efficiency (F8)1μm ≥90%Efficiency (H10)0.5μm ≥85%Efficiency (H12)0.5μm  ≥99.5%Efficiency (H13)0.3μm  ≥99.95%5VWGB592.592-292**592×592×2923000406011016022014004VWGB592.592-292**592×592×292240012004VWGB287.592-292**287×592×29212006006VXWGB610.610-292**610×610×292340018005VXWGB610.610-292**610×610×292300014004VXWGB610.610-292**610×610×292240012004VXWGB305.610-292**305×610×2921200600
